11.2 Patient Positioning, Draping, Needle Selection, Retention, and Removal

Key Takeaways

  • Treat first-time, anxious, weak, hungry, or tired patients lying down, because seated treatment raises the risk of fainting.

  • Expose only the area being treated, explain why exposure is needed, obtain consent, and leave the room or turn away while the patient undresses.

  • Chinese needle gauge numbers rise as needles get thinner (#36 is thinner than #30), while Japanese numbers rise as needles get thicker.

  • Adults are usually retained 15-30 minutes with regular checks; young children are usually not retained.

  • Remove needles in a consistent order, count them against the chart, press the site with dry cotton, and place each needle immediately in a sharps container.

11.2 Patient Positioning, Draping, Needle Selection, Retention, and Removal

Quick Answer: The 2026 ACPL outline includes positioning and draping, needle selection (length, gauge, filiform and other types), retention time, and removal (order, speed, pressure). Position patients so they are comfortable, stable, and lying down when there is any fainting risk. Drape so only the treated area is exposed, with consent. Choose the needle by location, depth, patient size and sensitivity, and technique. Retain adult needles for about 15-30 minutes while monitoring the patient. Remove needles in a consistent order, count them, and dispose of each one immediately in a sharps container.

Patient Positioning

PositionBest forPrecautions
SupineFace, chest, abdomen, front of the limbsBolster under the knees eases the low back; avoid after about 20 weeks of pregnancy
ProneBack, neck, back of the limbsFace cradle and a pillow under the ankles; difficult for breathing problems and late pregnancy
Side-lyingLateral points (GB channel, shoulder, hip), pregnancyPillow between the knees and under the head
SeatedHead, neck, shoulders, ear, brief treatments, patients who cannot lie downHighest fainting risk; use for brief or auricular treatment only in stable, experienced patients

Fainting (needle shock) risk factors: first treatment, anxiety, fear of needles, fatigue, hunger, dehydration, weakness, and strong stimulation. Treat these patients lying down.

Before inserting needles, make sure the patient is comfortable enough to stay still. Moving or changing position with needles in place can cause bent or stuck needles and pain. If the position must change, remove the needles first.

Draping and Exposure

  • Explain which areas you need to reach and why, and obtain consent. Respect cultural and personal preferences.
  • Leave the room or turn away while the patient changes, and provide a gown, sheet, or towel.
  • Expose only the area being treated, and keep the rest of the body covered for warmth and privacy.
  • Points near the breasts, groin, or buttocks need specific consent. Offer a chaperone, and follow your clinic policy and state law.
  • Keep the patient warm, especially during long retention times, because chilling increases discomfort and fainting risk.

Needle Anatomy and Types

A filiform needle has a tip, a body (shaft), a root where the body meets the handle, a handle, and a tail. Most broken needles snap at the root, so never insert a needle all the way to the handle.

Needle typeUse
Filiform (Hao Zhen)Standard acupuncture needle for most treatments
Three-edged (lancet) or lancet deviceBloodletting at Jing-Well points, Ear Apex, or Taiyang
Plum-blossom or seven-star (cutaneous) needleLight tapping over skin areas for skin conditions, hair loss, and children
Intradermal needles and press tacksRetained in the skin or ear for continuous mild stimulation
Fire needle (Huo Zhen)Heated needle inserted quickly, a specialized technique for Cold-Damp and some skin lesions
Guide tube (Japanese method)Plastic or metal tube that helps painless insertion

Ling Shu Chapter 1 describes the classical Nine Needles, which included cutting, round-tipped, and long needles; the modern filiform needle descends from the fine needle of this set.

Choosing Gauge and Length

FactorChoice
Thin areas (face, scalp, hands, feet, ear)Short (13-25 mm) and thin needles
Thick muscles (buttock, thigh)Longer needles (40-75 mm), such as for GB 30
Sensitive, frail, or young patientsThinner needles
Strong stimulation or trigger point needlingSlightly thicker needles that resist bending
Transverse or threading insertionLonger needles for the distance traveled

Gauge systems differ: in the Chinese numbering system, a higher number means a thinner needle (for example, #36 is thinner than #30). In the Japanese system, a higher number means a thicker needle. Many manufacturers now label needles by diameter in millimeters, commonly about 0.16-0.30 mm, and length in millimeters. The usual length conversions are 1 cun = 25 mm, 1.5 cun = 40 mm, and 3 cun = 75 mm.

Use only sterile, single-use, disposable needles, and check the package for intact seals and expiry dates.

Retention and Monitoring

  • Adults: usually 15-30 minutes. Shorter retention suits weak or sensitive patients; longer retention is used for some chronic pain and spasm.
  • Young children: generally no retention (quick in and out).
  • Restimulation: manually stimulate the needles every 5-10 minutes when stronger stimulation is needed.
  • Monitoring: check the patient regularly, give them a way to call for help, and never leave a patient with needles in place unattended for long. Watch for pallor, sweating, nausea, or faintness (signs of needle shock).

Removal

  1. Wash hands and put on gloves where there is any chance of contact with blood.
  2. Hold a dry cotton ball or gauze next to the needle with your non-dominant hand.
  3. Withdraw the needle smoothly, and press the site with the dry cotton. Reinforcing technique: withdraw slowly and press the hole quickly. Reducing technique: withdraw quickly, shaking the needle and leaving the hole open (Kai He Bu Xie, Section 11.1).
  4. Place each needle immediately in the sharps container. Do not recap.
  5. Follow a consistent order, such as top to bottom or the order of insertion, and count the needles removed against the number inserted. Check the hair, clothing, and table for missed needles.
  6. Apply firm pressure to sites that bleed, such as the head and ear. Use dry cotton, not alcohol, which delays clotting.
  7. Ask the patient to rest briefly and sit up slowly before standing.

A stuck needle (from muscle spasm or a twisted needle) is freed by relaxing the patient, massaging or inserting a needle near the site, or twirling the needle back in the opposite direction (Section 11.3).

Test Your Knowledge

A nervous first-time patient who skipped lunch is scheduled for treatment of neck pain. Which position is safest?

A

Seated, so the neck and shoulder points are easier to reach

B

Seated with the arms raised above the head to open the neck

C

Standing, so the patient can move about freely if they feel dizzy

D

Lying down, prone or side-lying, to reduce the fainting risk

Test Your Knowledge

A practitioner orders needles using the Chinese gauge numbering system. Which statement is correct?

A

A #36 needle is thicker than a #30 needle

B

Gauge numbers describe length, not diameter

C

Chinese and Japanese gauge numbers mean the same thing

D

A #36 needle is thinner than a #30 needle

Test Your Knowledge

After a treatment with 14 needles, the practitioner counts only 13 in the sharps container. What should happen next?

A

End the visit, since one missing needle out of fourteen is within an acceptable margin of error

B

Search the patient's body, hair, clothing, and the table before the patient leaves

C

Insert another needle to replace the missing one so the count matches the chart

D

Record 14 needles removed in the chart, since the count was probably miscounted

Remove the needles in random order without counting

C

Withdraw the needle and wipe the site with alcohol to stop bleeding

D

Withdraw slowly and press the hole closed quickly with dry cotton
